The thermal boundary conductance between a thin ⁴He film and its substrate
… 1.35 and 4.40 atomic layers shows that the boundary conductance between a thin film and its substrate is three to five orders of magnitude smaller than the boundary conductance between bulk liquid helium and a solid. The conductance for the bulk case is the reciprocal of the Kapitza …
